Overview
The MCP1641X is a compact, high-efficiency, fixed frequency, low-voltage, synchronous step-up DC-DC converter with battery monitoring features. It provides an easy-to-use power supply solution for applications over a wide range of inputs: single-cell, two-cell, alkaline/NiMH batteries or single-cell Li-Ion/Li-Polymer batteries can be used. With the 1A Typical Peak Input Current Limit, MCP1641X can provide over 200 mA output current in 3.3V applications with input over 1.5V
The MCP16411 Low IQ Boost with Programmable UVLO Evaluation Board has the following features:
• Input Voltage Range: 0.8V (after start-up) to 5.25V
• Typical 3.3V Output Voltage
• Output Current: 200 mA @ 3.3V VOUT with 1.5V VIN
• Enable state is selectable by using the ENABLE switch. When the EN pin is OFF, the MCP16411 will be in Output Discharge mode
• Automatic PFM/PWM Operation: - PFM for high efficiency at light loads
• Undervoltage Lockout (UVLO) is selectable by using the UVLO START-UP switch. The UVLO pin which is set to start-up at 0.85V (default value) and 1.1V (programmable value).
